P0493 Possible Solution:
Gasoline engines use spark plugs to cause an explosion of fuel within the cylinder. In a properly timed engine, this explosion occurs at the proper moment to send the piston to the bottom of the cylinder and provide power to the drive shaft.

The improper timing of the explosion sometimes pushes the cylinder the wrong direction or interferes with the turning of the crank. As a result, the engine stutters or backfires, if it runs at all.
P0493 Code Meaning :
|OBD-II Diagnostic Powertrain (P) Trouble Code For Engine||Intake Valve Control Solenoid Circuit Low||O2 Sensor Heater Circuit Malfunction||Crankshaft Position Sensor A Circuit Malfunction||Exhaust Gas Recirculation Sensor B Circuit High|
The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate.
P0493 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP0493 engine trouble code is about Exhaust Gas Recirculation Sensor B Circuit High.
Main reason For P0493 CodeThe reason of P0493 OBD-II Engine Trouble Code is O2 Sensor Heater Circuit Malfunction.
P0493 code on vehicles with electronically controlled automatic transmissions, the 3-4 shift solenoid is responsible for actuating the hydraulic circuits to activate clutches or bands that change gears inside the automatic transmission.
